Green plants, unlike most other living things, take IN carbon dioxide (which we expel), and they expel oxygen, which we then breathe. This recycling of the elements in air is the single most important thing that plants contribute to the ecosystem (although only slightly to a lesser extent they also help filter impurities out of the air).
